Abstract
A landing gear including a shock strut assembly including an outer cylinder coupled to an airframe, a wheel movably coupled to the outer cylinder so as to reciprocate substantially along a longitudinal axis of the outer cylinder, and a shrink mechanism including a pivot arm pivotally coupled to the shock strut assembly, a drive member coupling the pivot arm to a landing gear retract mechanism, a driven member coupled to the pivot arm, a first shrink link member coupled to the pivot arm by the driven member, and a second shrink link member coupled to the first shrink link member and to the shock strut assembly. Rotation of the pivot arm by the drive member, effects a folding movement between the first shrink link member and the second shrink link member, and the folding movement effects at least a retraction of the wheel relative to the outer cylinder.
